First Claim
Patent Images
1. An eyewear having a transparent component, the transparent component comprising:
- a linearly polarizing layer, anda birefringent layer,wherein a viewing direction of the eyewear extends perpendicularly through the linearly polarizing layer and the birefringent layer, andwherein a thickness of the birefringent layer in the viewing direction is selected to provide an optical path difference between an ordinary ray and an extraordinary ray in a range of from 400 nm to 1700 nm.

Abstract
A transparent component for eyeglasses is provided. The transparent component includes a birefringent layer and at least one linearly polarizing layer. Polarized light falling on the transparent component exhibits a color effect. Additionally, a second linearly polarizing layer may be provided such that the birefringent layer is sandwiched between the linearly polarizing layer and the second linearly polarizing layer. When the second linearly polarizing layer is provided, non-polarized light falling on the transparent component also exhibits a color effect.
